Example This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem or hold all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same. You may be required to pay brokerage commissions on your purchases and sales of Class F-2, F-3, 529-F-2 or 529-F-3 shares of the fund, which are not reflected in the example. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio turnover The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s investment results. During the most recent fiscal year, the fund’s portfolio turnover rate was 92% of the average value of its portfolio.

Principal investment strategies Normally the fund invests primarily in income-producing securities. These include equity securities, such as dividend-paying common stocks, and debt securities, such as interest-paying bonds.

Generally at least 60% of the fund’s assets will be invested in common stocks and other equity-type securities. However, the composition of the fund’s investments in equity, debt and cash or money market instruments may vary substantially depending on various factors, including market conditions. The fund may also invest up to 30% of its assets in common stocks and other equity-type securities of issuers domiciled outside the United States, including issuers in emerging markets. In addition, the fund may invest up to 20% of its assets in lower quality, higher yielding nonconvertible debt securities (rated Ba1 and BB+ or below by Nationally Recognized Statistical Rating Organizations designated by the fund’s investment adviser or unrated but determined to be of equivalent quality by the fund’s investment adviser); such securities are sometimes referred to as “junk bonds.” The fund may also invest up to 10% of its assets in debt securities tied economically to countries outside the United States; however, these securities must be denominated in U.S. dollars.

The investment adviser uses a system of multiple portfolio managers in managing the fund’s assets. Under this approach, the portfolio of the fund is divided into segments managed by individual managers.

The Income Fund of America / Prospectus 2

Principal risks This section describes the principal risks associated with investing in the fund. You may lose money by investing in the fund. The likelihood of loss may be greater if you invest for a shorter period of time.

Market conditions — The prices of, and the income generated by, the common stocks and other securities held by the fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Economic, financial or political events, trading and tariff arrangements, wars, terrorism, cybersecurity events, natural disasters, public health emergencies (such as the spread of infectious disease), bank failures and other circumstances in one country or region, including actions taken by governmental or quasi-governmental authorities in response to any of the foregoing, could have impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of the fund’s investments may be negatively affected by developments in other countries and regions.

Issuer risks — The prices of, and the income generated by, securities held by the fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer’s goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer’s financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets may be affected by a change in financial condition or other event affecting a single issuer.

Investing in income-oriented stocks — The value of the fund’s securities and income provided by the fund may be reduced by changes in the dividend policies of, and the capital resources available for dividend payments at, the companies in which the fund invests.

Investing in debt instruments — The prices of, and the income generated by, bonds and other debt securities held by the fund may be affected by factors such as the interest rates, maturities and credit quality of these securities.

Rising interest rates will generally cause the prices of bonds and other debt securities to fall. Also, when interest rates rise, issuers of debt securities that may be prepaid at any

3 The Income Fund of America / Prospectus

time, such as mortgage- or other asset-backed securities, are less likely to refinance existing debt securities, causing the average life of such securities to extend. A general change in interest rates may cause investors to sell debt securities on a large scale, which could also adversely affect the price and liquidity of debt securities and could also result in increased redemptions from the fund. Falling interest rates may cause an issuer to redeem, call or refinance a debt security before its stated maturity, which may result in the fund having to reinvest the proceeds in lower yielding securities. Longer maturity debt securities generally have greater sensitivity to changes in interest rates and may be subject to greater price fluctuations than shorter maturity debt securities.

Bonds and other debt securities are also subject to credit risk, which is the possibility that the credit strength of an issuer or guarantor will weaken or be perceived to be weaker, and/or an issuer of a debt security will fail to make timely payments of principal or interest and the security will go into default. Changes in actual or perceived creditworthiness may occur quickly. A downgrade or default affecting any of the fund’s securities could cause the value of the fund’s shares to decrease. Lower quality debt securities generally have higher rates of interest and may be subject to greater price fluctuations than higher quality debt securities. Credit risk is gauged, in part, by the credit ratings of the debt securities in which the fund invests. However, ratings are only the opinions of the rating agencies issuing them and are not guarantees as to credit quality or an evaluation of market risk. The fund’s investment adviser relies on its own credit analysts to research issuers and issues in assessing credit and default risks.

Investing in lower rated debt instruments — Lower rated bonds and other lower rated debt securities generally have higher rates of interest and involve greater risk of default or price declines due to changes in the issuer’s creditworthiness than those of higher quality debt securities. The market prices of these securities may fluctuate more than the prices of higher quality debt securities and may decline significantly in periods of general economic difficulty. These risks may be increased with respect to investments in junk bonds.

Investing outside the United States — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different regulatory, legal, accounting, auditing, financial reporting and recordkeeping requirements, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could

The Income Fund of America / Prospectus 4

impact the liquidity of the fund’s portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

Management — The investment adviser to the fund actively manages the fund’s investments. Consequently, the fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

Your investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, entity or person. You should consider how this fund fits into your overall investment program.

Investment results The following bar chart shows how the fund’s investment results have varied from year to year, and the following table shows how the fund’s average annual total returns for various periods compare with a broad measure of securities market results and other applicable measures of market results. This information provides some indication of the risks of investing in the fund. Past investment results (before and after taxes) are not predictive of future investment results. Prior to October 30, 2020, certain fees, such as 12b-1 fees, were not charged on Class 529-F-1 shares. If these expenses had been deducted, results would have been lower. Updated information on the fund’s investment results can be obtained by visiting capitalgroup.com.

* Effective July 24, 2024, the fund’s primary benchmark changed from the 65%/35% S&P 500 Index/Bloomberg U.S. Aggregate Index (the “Previous Primary Benchmark”) to the S&P 500 Index, a broad-based index that represents the overall securities markets, as required by the U.S. Securities and Exchange Commission (“SEC”). The Previous Primary Benchmark provides a means to compare the fund’s results to a benchmark that the investment adviser believes is more representative of the fund’s investment universe. There is no change in the fund’s investment strategies as a result of the benchmark change.

After-tax returns are shown only for Class F-2 shares; after-tax returns for other share classes will vary. After-tax returns are calculated using the highest individual federal income tax rates in effect during each year of the periods shown and do not reflect the impact of state and local taxes. Your actual after-tax returns depend on your individual tax situation and likely will differ from the results shown above. In addition, after-tax

Investment objectives, strategies and risks The fund’s investment objectives are to provide you with current income while secondarily striving for capital growth. While it has no present intention to do so, the fund’s board may change the fund’s investment objectives without shareholder approval upon 60 days’ prior written notice to shareholders. Normally the fund invests primarily in income-producing securities. These include equity securities, such as dividend-paying common stocks, and debt securities, such as interest-paying bonds.

The fund may also hold cash or cash equivalents, including commercial paper and short-term securities issued by the U.S. government, its agencies and instrumentalities. The percentage of the fund invested in such holdings varies and depends on various factors, including market conditions and purchases and redemptions of fund shares. The investment adviser may determine that it is appropriate to invest a substantial portion of the fund’s assets in such instruments in response to certain circumstances, such as periods of market turmoil. For temporary defensive purposes, the fund may invest without limitation in such instruments. A larger percentage of such holdings could moderate the fund’s investment results in a period of rising market prices. Alternatively, a larger percentage of such holdings could reduce the magnitude of the fund’s loss in a period of falling market prices and provide liquidity to make additional investments or to meet redemptions.

The fund may invest in certain other funds managed by the investment adviser or its affiliates (“Central Funds”) to more effectively invest in a diversified set of securities in a specific asset class such as money market instruments, bonds and other securities. Shares of Central Funds are only offered for purchase to the fund’s investment adviser and its affiliates and other funds, investment vehicles and accounts managed by the fund’s investment adviser and its affiliates. Central Funds do not charge management fees. As a result, the fund does not bear additional management fees when investing in Central Funds, but the fund does bear its proportionate share of Central Fund expenses. The investment results of the portions of the fund’s assets invested in the Central Funds will be based upon the investment results of the Central Funds.

The fund may also lend portfolio securities to brokers, dealers and other institutions that provide cash or U.S. Treasury securities as collateral in an amount at least equal to the value of the securities loaned.

The Income Fund of America / Prospectus 8

The fund relies on the professional judgment of its investment adviser to make decisions about the fund’s portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. The investment adviser believes that an important way to accomplish this is through fundamental analysis, which may include meeting with company executives and employees, suppliers, customers and competitors. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

The investment adviser may consider environmental, social and governance (“ESG”) factors that, depending on the facts and circumstances, are material to the value of an issuer or instrument. ESG factors may include, but are not limited to, environmental issues (e.g., water use, emission levels, waste, environmental remediation), social issues (e.g., human capital, health and safety, changing customer behavior) or governance issues (e.g., board composition, executive compensation, shareholder dilution).

The following are principal risks associated with investing in the fund.

Rising interest rates will generally cause the prices of bonds and other debt securities to fall. Also, when interest rates rise, issuers of debt securities that may be prepaid at any time, such as mortgage- or other asset-backed securities, are less likely to refinance existing debt securities, causing the average life of such securities to extend. A general change in interest rates may cause investors to sell debt securities on a large scale, which could also adversely affect the price and liquidity of debt securities and could also result in increased redemptions from the fund. Falling interest rates may cause an issuer to redeem, call or refinance a debt security before its stated maturity, which may result in the fund having to reinvest the proceeds in lower yielding securities. Longer maturity debt securities generally have greater sensitivity to changes in interest rates and may be subject to greater price fluctuations than shorter maturity debt securities.

The Income Fund of America / Prospectus 10

more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could impact the liquidity of the fund’s portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

The following are additional risks associated with investing in the fund.

Investing in emerging markets — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The fund’s rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the fund’s net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

Exposure to country, region, industry or sector — Subject to the fund’s investment limitations, the fund may have significant exposure to a particular country, region, industry or sector. Such exposure may cause the fund to be more impacted by risks relating to and developments affecting the country, region, industry or sector, and thus its net asset value may be more volatile, than a fund without such levels of exposure. For example, if the fund has significant exposure in a particular country, then social,

11 The Income Fund of America / Prospectus

economic, regulatory or other issues that negatively affect that country may have a greater impact on the fund than on a fund that is more geographically diversified.

Interest rate risk — The values and liquidity of the securities held by the fund may be affected by changing interest rates. For example, the values of debt securities may decline when interest rates rise and increase when interest rates fall. Longer maturity debt securities generally have greater sensitivity to changes in interest rates and may be subject to greater price fluctuations than shorter maturity debt securities. The fund may invest in variable and floating rate securities. When the fund holds variable or floating rate securities, a decrease in market interest rates will adversely affect the income received from such securities and the net asset value of the fund’s shares. Although the values of such securities are generally less sensitive to interest rate changes than those of other debt securities, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as market interest rates. Conversely, floating rate securities will not generally increase in value if interest rates decline. During periods of extremely low short-term interest rates, certain of the fund’s debt securities may not be able to maintain a positive yield or total return and, in relatively low interest rate environments, there are heightened risks associated with rising interest rates.

Liquidity risk — Certain fund holdings may be or may become difficult or impossible to sell, particularly during times of market turmoil. Liquidity may be impacted by the lack of an active market for a holding, legal or contractual restrictions on resale, or the reduced number and capacity of market participants to make a market in such holding. Market prices for less liquid or illiquid holdings may be volatile or difficult to determine, and reduced liquidity may have an adverse impact on the market price of such holdings. Additionally, the sale of less liquid or illiquid holdings may involve substantial delays (including delays in settlement) and additional costs and the fund may be unable to sell such holdings when necessary to meet its liquidity needs or to try to limit losses, or may be forced to sell at a loss.

Lending of portfolio securities — Securities lending involves risks, including the risk that the loaned securities may not be returned in a timely manner or at all, which would interfere with the fund’s ability to vote proxies or settle transactions, and/or the risk of a counterparty default. Additionally, the fund may lose money from the reinvestment of collateral received on loaned securities in investments that decline in value, default or do not perform as expected.

Cybersecurity breaches — The fund may be subject to operational and information security risks through breaches in cybersecurity. Cybersecurity breaches can result from deliberate attacks or unintentional events, including “ransomware” attacks, the injection of computer viruses or malicious software code, the use of vulnerabilities in code to gain unauthorized access to digital information systems, networks or devices, or external attacks such as denial-of-service attacks on the investment adviser’s or an affiliate’s website that could render the fund’s network services unavailable to intended end-users. These breaches may, among other things, lead to the unauthorized release of confidential information, misuse of the fund’s assets or sensitive information, the disruption of the fund’s operational capacity, the inability of fund shareholders to transact business, or the destruction of the fund’s physical infrastructure, equipment or operating systems. These events could cause the fund to violate applicable privacy and other laws and could subject the fund to reputational damage, additional costs associated with corrective measures and/or financial loss. The fund may also be subject

The Income Fund of America / Prospectus 12

to additional risks if its third-party service providers, such as the fund’s investment adviser, transfer agent, custodian, administrators and other financial intermediaries, experience similar cybersecurity breaches and potential outcomes. Cybersecurity risks may also impact issuers of securities in which the fund invests, which may cause the fund’s investments in such issuers to lose value.

Large shareholder transactions risk — The fund may experience adverse effects when shareholders, including other funds or accounts advised by the investment adviser, purchase or redeem, individually or in the aggregate, large amounts of shares relative to the size of the fund. For example, when the investment adviser changes allocations in other funds and accounts it manages, such changes may result in shareholder transactions in the fund that are large relative to the size of the fund. Such large shareholder redemptions may cause the fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the fund’s net asset value and liquidity. Similarly, large fund share purchases may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the fund’s current expenses being allocated over a smaller asset base, leading to an increase in the fund’s expense ratio. These risks are heightened when the fund is small.

In addition to the principal investment strategies described above, the fund has other investment practices that are described in the statement of additional information, which includes a description of other risks related to the fund’s principal investment strategies and other investment practices. The fund’s investment results will depend on the ability of the fund’s investment adviser to navigate the risks discussed above as well as those described in the statement of additional information.

Fund comparative indexes The investment results table in this prospectus shows how the fund’s average annual total returns compare with a broad measure of market results and other applicable measures of market results. The S&P 500 Index is a market capitalization-weighted index based on the results of approximately 500 widely held common stocks. This index is unmanaged, and its results include reinvested dividends and/or distributions but do not reflect the effect of sales charges, commissions, account fees, expenses or U.S. federal income taxes. The 65%/35% S&P 500 Index/Bloomberg U.S. Aggregate Index blends the S&P 500 Index with the Bloomberg U.S. Aggregate Index by weighting their cumulative total returns at 65% and 35%, respectively. This assumes the blend is rebalanced monthly. The Bloomberg U.S. Aggregate Index represents the U.S. investment-grade fixed-rate bond market. This index is unmanaged, and its results include reinvested dividends and/or distributions but do not reflect the effect of sales charges, commissions, account fees, expenses or U.S. federal income taxes.

Management and organization

Investment adviser Capital Research and Management Company, an experienced investment management organization founded in 1931, serves as the investment adviser to the fund and other funds, including the American Funds. Capital Research and Management Company is a wholly owned subsidiary of The Capital Group Companies, Inc. and is located at 333 South Hope Street, Los Angeles, California 90071. Capital Research and Management Company manages the investment portfolio and business affairs of the fund. The total management fee paid by the fund to its investment adviser for the most recent fiscal year, as a percentage of average net assets, appears in the Annual Fund Operating Expenses table under “Fees and expenses of the fund.” As described more fully in the fund’s statement of additional information, the management fee is based on the daily net assets of the fund and the fund’s monthly gross investment income. A discussion regarding the basis for approval of the fund’s Investment Advisory and Service Agreement by the fund’s board of trustees is contained in the fund’s Form N-CSR for the fiscal period ended January 31, 2024.

Capital Research and Management Company manages equity assets through three equity investment divisions and fixed income assets through its fixed income investment division, Capital Fixed Income Investors. The three equity investment divisions — Capital International Investors, Capital Research Global Investors and Capital World Investors — make investment decisions independently of one another.

The equity investment divisions may, in the future, be incorporated as wholly owned subsidiaries of Capital Research and Management Company. In that event, Capital Research and Management Company would continue to be the investment adviser, and day-to-day investment management of equity assets would continue to be carried out through one or more of these subsidiaries. Although not currently contemplated, Capital Research and Management Company could incorporate its fixed income investment division in the future and engage it to provide day-to-day investment management of fixed income assets. Capital Research and Management Company and each of the funds it advises have received an exemptive order from the U.S. Securities and Exchange Commission that allows Capital Research and Management Company to use, upon approval of the fund’s board, its management subsidiaries and affiliates to provide day-to-day investment management services to the fund, including making changes to the management subsidiaries and affiliates providing such services. The fund’s shareholders have approved this arrangement; however, there is no assurance that Capital Research and Management Company will incorporate its investment divisions or exercise any authority granted to it under the exemptive order.

Certain privileges and/or services described on the following pages of this prospectus and in the statement of additional information may not be available to you, depending on your investment dealer or retirement plan recordkeeper. Please see your financial professional or retirement plan recordkeeper for more information.

Shareholder information

Shareholder services American Funds Service Company, the fund’s transfer agent, offers a wide range of services that you can use to alter your investment program should your needs or circumstances change. These services may be terminated or modified at any time upon 60 days’ prior written notice.

A more detailed description of policies and services is included in the fund’s statement of additional information and the owner’s guide sent to new American Funds shareholders entitled Welcome. Class 529 shareholders should also refer to the applicable program description for information on policies and services relating specifically to their account(s). These documents are available by writing to or calling American Funds Service Company.

The Income Fund of America / Prospectus 18

Unless otherwise noted or unless the context requires otherwise, references on the following pages to (i) Class A, C, T or F shares also refer to the corresponding Class 529-A, 529-C, 529-T or 529-F shares, (ii) Class F shares refer to Class F-1, F-2 and F-3 shares and (iii) Class R shares refer to Class R-1, R-2, R-2E, R-3, R-4, R-5E, R-5 and R-6 shares.

Purchase, exchange and sale of shares The fund’s transfer agent, on behalf of the fund and Capital Client Group, Inc., the fund’s distributor, is required by law to obtain certain personal information from you or any other person(s) acting on your behalf in order to verify your identity or such other person’s identity. If you do not provide the information, the transfer agent may not be able to open your account. If the transfer agent is unable to verify your identity or that of any other person(s) authorized to act on your behalf, or believes it has identified potentially criminal activity, the fund and Capital Client Group, Inc. reserve the right to close your account or take such other action they deem reasonable or required by law.

When purchasing shares, you should designate the fund or funds in which you wish to invest. Subject to the exception below, if no fund is designated, your money will be held uninvested (without liability to the transfer agent for loss of income or appreciation pending receipt of proper instructions) until investment instructions are received, but for no more than three business days. Your investment will be made at the net asset value (plus any applicable sales charge, in the case of Class A or Class T shares) next determined after investment instructions are received and accepted by the transfer agent. If investment instructions are not received, your money will be invested in Class A shares (or, if you are investing through a financial intermediary who offers only Class T shares, in Class T shares) of American Funds^® U.S. Government Money Market Fund on the third business day after receipt of your investment.

If the amount of your cash investment is $10,000 or less, no fund is designated, and you made a cash investment (excluding exchanges) within the last 16 months, your money will be invested in the same proportion and in the same fund or funds and in the same class of shares in which your last cash investment was made. If you only have one open fund, the money will be invested into such fund on the day received if the investment is otherwise in good order.

Different procedures may apply to certain employer-sponsored arrangements, including, but not limited to, SEPs and SIMPLE IRAs.

Valuing shares The net asset value of each share class of the fund is the value of a single share of that class. The net asset value per share is calculated once daily as of the close of regular trading on the New York Stock Exchange, normally 4 p.m. New York time, each day the New York Stock Exchange is open. If the New York Stock Exchange makes a scheduled (e.g., the day after Thanksgiving) or an unscheduled close prior to 4 p.m. New York time, the net asset value of the fund will be determined at approximately the time the New York Stock Exchange closes on that day. If on such a day market quotations and prices from third-party pricing services are not based as of the time of the early close of the New York Stock Exchange but are as of a later time (up to approximately 4 p.m. New York time), for example because the market remains open after the close of the New York Stock Exchange, those later market quotations and prices will be used in determining the fund’s net asset value.

19 The Income Fund of America / Prospectus

Equity securities are valued primarily on the basis of market quotations, and debt securities are valued primarily on the basis of prices from third-party pricing services due to the lack of market quotations. Futures contracts are valued primarily on the basis of settlement prices. The fund’s portfolio investments are valued in accordance with procedures for making fair value determinations if market quotations are not readily available, including procedures to determine the representativeness of third-party vendor prices, or in the event market quotations or third-party vendor prices are not considered reliable. For example, if events occur between the close of markets outside the United States and the close of regular trading on the New York Stock Exchange that, in the opinion of the investment adviser, materially affect the value of any of the fund’s equity securities that trade principally in those international markets, those securities will be valued in accordance with fair value procedures. Similarly, fair value procedures will be employed if an issuer defaults on its debt securities and there is no market for its securities. Use of these procedures is intended to result in more appropriate net asset values and, where applicable, to reduce potential arbitrage opportunities otherwise available to short-term investors.

Because the fund may hold securities that are listed primarily on foreign exchanges that trade on weekends or days when the fund does not price its shares, the values of securities held in the fund may change on days when you will not be able to purchase or redeem fund shares.

Your shares will be purchased at the net asset value (plus any applicable sales charge, in the case of Class A or Class T shares) or sold at the net asset value next determined after American Funds Service Company receives your request, provided that your request contains all information and legal documentation necessary to process the transaction. Orders in good order received after the New York Stock Exchange closes (scheduled or unscheduled) will be processed at the net asset value (plus any applicable sales charge) calculated on the following business day. A contingent deferred sales charge may apply at the time you sell certain Class A and C shares.

Purchase of Class A and C shares You may generally open an account and purchase Class A and C shares by contacting any financial professional (who may impose transaction charges in addition to those described in this prospectus) authorized to sell the fund’s shares. You may purchase additional shares in various ways, including through your financial professional and by mail, telephone, the Internet and bank wire.

Automatic conversion of Class C and Class 529-C shares Class C shares automatically convert to Class A shares in the month of the 8-year anniversary of the purchase date. Class 529-C shares automatically convert to Class 529-A shares, in the month of the 5-year anniversary of the purchase date. The Internal Revenue Service currently takes the position that such automatic conversions are not taxable. Should its position change, the automatic conversion feature may be suspended. If this were to happen, you would have the option of converting your Class C shares to Class A shares or your Class 529-C shares to Class 529-A shares at the anniversary date described above. This exchange would be based on the relative net asset values of the two classes in question, without the imposition of a sales charge or fee, but you might face certain tax consequences as a result.

Purchase of Class F shares You may generally open an account and purchase Class F shares only through fee-based programs of investment dealers that have special

The Income Fund of America / Prospectus 20

agreements with the fund’s distributor, through financial intermediaries that have been approved by, and that have special agreements with, the fund’s distributor to offer Class F shares to self-directed investment brokerage accounts that may charge a transaction fee, through certain registered investment advisors and through other intermediaries approved by the fund’s distributor. These intermediaries typically charge ongoing fees for services they provide. Intermediary fees are not paid by the fund and normally range from .75% to 1.50% of assets annually, depending on the services offered.

Class F-2, F-3, 529-F-2 and 529-F-3 shares may also be available on brokerage platforms of firms that have agreements with the fund’s distributor to offer such shares solely when acting as an agent for the investor. An investor transacting in Class F-2, F-3, 529-F-2 or 529-F-3 shares in these programs may be required to pay a commission and/or other forms of compensation to the broker. Shares of the fund are available in other share classes that have different fees and expenses.

In addition, upon approval by an officer of the fund’s investment adviser, Class F-3 shares (but not Class 529-F-3 shares) are available to institutional investors, which include, but are not limited to, charitable organizations, governmental institutions, corporations and financial intermediaries. For accounts held and serviced by the fund’s transfer agent the minimum investment amount is $1 million.

Purchase of Class 529 shares Class 529 shares may be purchased only through an account established with a 529 college savings plan managed by Capital Research and Management Company. You may open this type of account and purchase Class 529 shares by contacting any financial professional (who may impose transaction charges in addition to those described in this prospectus) authorized to sell such an account. You may purchase additional shares in various ways, including through your financial professional and by mail, telephone, the Internet and bank wire.

Class 529-E shares may be purchased only by employees participating through an eligible employer plan.

Accounts holding Class 529 shares are subject to a $10 account setup fee and an annual $10 account maintenance fee. These fees are waived until further notice.

Investors residing in any state may purchase Class 529 shares through an account established with a 529 college savings plan managed by Capital Research and Management Company. Class 529-A, 529-C, 529-T and 529-F shares are structured similarly to the corresponding Class A, C, T and F shares.

Purchase of Class R shares Class R shares are generally available only to retirement plans established under Internal Revenue Code Sections 401(a), 403(b) or 457, and to nonqualified deferred compensation plans and certain voluntary employee benefit association and post-retirement benefit plans. Class R shares also are generally available only to retirement plans for which plan level or omnibus accounts are held on the books of the fund. Class R-5E, R-5 and R-6 shares are generally available only to fee-based programs or through retirement plan intermediaries. Class R-3 and Class R-5E shares are available through the American Funds SIMPLE IRA Plus Program and other similar programs. In addition, Class R-5 and R-6 shares are available for investment by other registered investment companies and collective investment trusts approved by the fund’s investment adviser or distributor. Except as otherwise provided in this prospectus,

21 The Income Fund of America / Prospectus

Class R shares are generally not available for purchase to retail nonretirement accounts; traditional and Roth individual retirement accounts (IRAs); Coverdell Education Savings Accounts; SEPs, SARSEPs and SIMPLE IRAs held in brokerage accounts; and 529 college savings plans. Class R-6 shares are available to employer-sponsored SEPs, SARSEPs and SIMPLE IRAs held in fee-based programs that are serviced through retirement plan recordkeepers.

Purchases by employer-sponsored retirement plans Eligible retirement plans generally may open an account and purchase Class A or R shares by contacting any investment dealer (who may impose transaction charges in addition to those described in this prospectus) authorized to sell these classes of the fund’s shares. Some or all R share classes may not be available through certain investment dealers. Additional shares may be purchased through a plan’s administrator or recordkeeper.

Class A shares are generally not available for retirement plans using the PlanPremier^® or Recordkeeper Direct^® recordkeeping programs. These programs are proprietary recordkeeping solutions for small retirement plans.

Employer-sponsored retirement plans that are eligible to purchase Class R shares may instead purchase Class A shares and pay the applicable Class A sales charge, provided that their recordkeepers can properly apply a sales charge on plan investments. These plans are not eligible to make initial purchases of $1 million or more in Class A shares and thereby invest in Class A shares without a sales charge, nor are they eligible to establish a statement of intention that qualifies them to purchase Class A shares without a sales charge. More information about statements of intention can be found under “Sales charge reductions and waivers” in this prospectus. Plans investing in Class A shares with a sales charge may purchase additional Class A shares in accordance with the sales charge table in this prospectus.

Employer-sponsored retirement plans that invested in American Funds Class A shares without any sales charge before April 1, 2004, and that continue to meet the eligibility requirements in effect as of that date for purchasing Class A shares at net asset value, may continue to purchase American Funds Class A shares without any initial or contingent deferred sales charge.

A 403(b) plan may not invest in American Funds Class A or C shares unless it was invested in Class A or C shares before January 1, 2009.

The Income Fund of America / Prospectus 22

Purchase minimums and maximums Purchase minimums described in this prospectus may be waived in certain cases. Minimums are currently waived for purchases of Class F-2 and F-3 shares held under fee-based programs. In addition, the fund reserves the right to redeem the shares of any shareholder for their then current net asset value per share if the shareholder’s aggregate investment in the fund falls below the fund’s minimum initial investment amount. See the statement of additional information for details.

For accounts established with an automatic investment plan, the initial purchase minimum of $250 may be waived if the purchases (including purchases through exchanges from another fund) made under the plan are sufficient to reach $250 within five months of account establishment.

The effective purchase maximums for Class 529-A, 529-C, 529-E, 529-T and 529-F shares will reflect the maximum applicable contribution limits under state law. See the applicable program description for more information.

If you have significant American Funds holdings, you may not be eligible to invest in Class C or 529-C shares. Specifically, you may not purchase Class C or 529-C shares if you are eligible to purchase Class A or 529-A shares at net asset value. See “Sales charge reductions and waivers” in this prospectus and the statement of additional information for more details regarding sales charge discounts.

23 The Income Fund of America / Prospectus

Exchange Except for Class T shares or as otherwise described in this prospectus, you may exchange your shares for shares of the same class of other American Funds without a sales charge. Class A, C, T or F shares of any American Fund (other than American Funds U.S. Government Money Market Fund, as described below) may be exchanged for the corresponding 529 share class without a sales charge. Exchanges from Class A, C, T or F shares to the corresponding 529 share class, particularly in the case of Uniform Gifts to Minors Act or Uniform Transfers to Minors Act custodial accounts, may result in significant legal and tax consequences, as described in the applicable program description. Please consult your financial professional before making such an exchange.

Except as indicated above, Class T shares are not eligible for exchange privileges. Accordingly, an exchange of your Class T shares for Class T shares of any other American Funds will normally be subject to any applicable sales charges.

Exchanges of shares from American Funds U.S. Government Money Market Fund initially purchased without a sales charge to shares of other American Funds will be subject to the appropriate sales charge applicable to the other fund, unless the American Funds U.S. Government Money Market Fund shares were acquired by an exchange from a fund having a sales charge or by reinvestment or cross-reinvestment of dividends or capital gain distributions. For purposes of computing the contingent deferred sales charge on Class C shares, the length of time you have owned your shares will be measured from the first day of the month in which shares were purchased and will not be affected by any permitted exchange.

Exchanges have the same tax consequences as ordinary sales and purchases. For example, to the extent you exchange shares held in a taxable account that are worth more now than what you paid for them, the gain will be subject to taxation.

See “Transactions by telephone, fax or the Internet” in the section “How to sell shares” of this prospectus for information regarding electronic exchanges.

Please see the statement of additional information for details and limitations on moving investments in certain share classes to different share classes and on moving investments held in certain accounts to different accounts.

How to sell shares

You may sell (redeem) shares in any of the following ways:

Employer-sponsored retirement plans

Shares held in eligible retirement plans may be sold through the plan’s administrator or recordkeeper.

Through your dealer or financial advisor (certain charges may apply)

· Shares held for you in your dealer’s name must be sold through the dealer.

· Class F shares must be sold through intermediaries such as dealers or financial advisors.

Writing to American Funds Service Company

· Requests must be signed by the registered shareholder(s).

· A signature guarantee is required if the redemption is:

— more than $250,000;

— made payable to someone other than the registered shareholder(s); or

— sent to an address other than the address of record or to an address of record that has been changed within the previous 10 days.

· American Funds Service Company reserves the right to require signature guarantee(s) on any redemption.

· Additional documentation may be required for redemptions of shares held in corporate, partnership or fiduciary accounts.

Telephoning or faxing American Funds Service Company

· Redemptions by telephone or fax are limited to $250,000 per American Funds shareholder each day.

· Checks must be made payable to the registered shareholder.

· Checks must be mailed to an address of record that has been used with the account for at least 10 days.

Self service using the Internet (capitalgroup.com) or Interactive Voice Response (IVR)

· Redemptions by IVR or the Internet (capitalgroup.com) are limited to $125,000 per American Funds shareholder each day.

· Checks must be made payable to the registered shareholder.

· Checks must be mailed to an address of record that has been used with the account for at least 10 days.

The fund typically expects to remit redemption proceeds one business day following receipt and acceptance of a redemption order, regardless of the method the fund uses to make such payment (e.g., check, wire or automated clearing house transfer). However, payment may take longer than one business day and may take up to seven days as generally permitted by the Investment Company Act of 1940, as amended (the “1940 Act”). Under the 1940 Act, the fund may be permitted to pay redemption proceeds beyond seven days under certain limited circumstances. In addition, if you recently purchased shares and subsequently request a redemption of those shares, the fund will pay the available redemption proceeds once a sufficient period of time has passed to

25 The Income Fund of America / Prospectus

reasonably ensure that checks or drafts, including certified or cashier’s checks, for the shares purchased have cleared (normally seven business days from the purchase date).

Under normal conditions, the fund typically expects to meet shareholder redemptions by monitoring the fund’s portfolio and redemption activities and by regularly holding a reserve of highly liquid assets, such as cash or cash equivalents. The fund may use additional methods to meet shareholder redemptions, if they become necessary. These methods may include, but are not limited to, the sale of portfolio assets, the use of overdraft protection afforded by the fund’s custodian bank, borrowing from a line of credit or from other funds advised by the investment adviser or its affiliates, and making payment with fund securities or other fund assets rather than in cash (as further discussed in the following paragraph).

Although payment of redemptions normally will be in cash, the fund’s declaration of trust permits payment of the redemption price wholly or partly with portfolio securities or other fund assets under conditions and circumstances determined by the fund’s board of trustees. On the same redemption date, some shareholders may be paid in whole or in part in securities (which may differ among those shareholders), while other shareholders may be paid entirely in cash. In general, in-kind redemptions to affiliated shareholders will as closely as practicable represent the affiliated shareholder’s pro rata share of the fund’s securities, subject to certain exceptions. Securities distributed in-kind to unaffiliated shareholders will be selected by the investment adviser in a manner the investment adviser deems to be fair and reasonable to the fund’s shareholders. The disposal of the securities received in-kind may be subject to brokerage costs and, until sold, such securities remain subject to market risk and liquidity risk, including the risk that such securities are or become difficult to sell. If the fund pays your redemption with illiquid or less liquid securities, you will bear the risk of not being able to sell such securities.

Transactions by telephone, fax or the Internet Generally, you are automatically eligible to redeem or exchange shares by telephone, fax or the Internet, unless you notify us in writing that you do not want any or all of these services. You may reinstate these services at any time.

Unless you decide not to have telephone, fax or Internet services on your account(s), you agree to hold the fund, American Funds Service Company, any of its affiliates or mutual funds managed by such affiliates, and each of their respective directors, trustees, officers, employees and agents harmless from any losses, expenses, costs or liabilities (including attorney fees) that may be incurred in connection with the exercise of these privileges, provided that American Funds Service Company employs reasonable procedures to confirm that the instructions received from any person with appropriate account information are genuine. If reasonable procedures are not employed, American Funds Service Company and/or the fund may be liable for losses due to unauthorized or fraudulent instructions.

Frequent trading of fund shares The fund and Capital Client Group, Inc. reserve the right to reject any purchase order for any reason. The fund is not designed to serve as a vehicle for frequent trading. Frequent trading of fund shares may lead to increased costs to the fund and less efficient management of the fund’s portfolio, potentially resulting in dilution of the value of the shares held by long-term shareholders. Accordingly, purchases, including those that are part of exchange activity, that the fund or Capital Client Group, Inc. has determined could involve actual or potential harm to the fund may be rejected.

The fund, through its transfer agent, American Funds Service Company, maintains surveillance procedures that are designed to detect frequent trading in fund shares. Under these procedures, various analytics are used to evaluate factors that may be indicative of frequent trading. For example, transactions in fund shares that exceed certain monetary thresholds may be scrutinized. American Funds Service Company also may review transactions that occur close in time to other transactions in the same account or in multiple accounts under common ownership or influence. Trading activity that is identified through these procedures or as a result of any other information available to the fund will be evaluated to determine whether such activity might constitute frequent trading. These procedures may be modified from time to time as appropriate to improve the detection of frequent trading, to facilitate monitoring for frequent trading in particular retirement plans or other accounts and to comply with applicable laws.

Under the fund’s frequent trading policy, certain trading activity will not be treated as frequent trading, such as:

· transactions in Class 529 shares;

· purchases and redemptions by investment companies managed or sponsored by the fund’s investment adviser or its affiliates, including reallocations and transactions allowing the investment company to meet its redemptions and purchases;

· retirement plan contributions, loans and distributions (including hardship withdrawals) identified as such on the retirement plan recordkeeper’s system;

· purchase transactions involving in-kind transfers of shares of the fund, rollovers, Roth IRA conversions and IRA recharacterizations, if the entity maintaining the shareholder account is able to identify the transaction as one of these types of transactions;

· transactions by certain intermediaries in accordance with established hedging programs approved by the fund’s investment adviser; and

· systematic redemptions and purchases, if the entity maintaining the shareholder account is able to identify the transaction as a systematic redemption or purchase.

Generally, purchases and redemptions will not be considered “systematic” unless the transaction is prescheduled for a specific date.

American Funds Service Company will work with certain intermediaries (such as investment dealers holding shareholder accounts in street name, retirement plan recordkeepers, insurance company separate accounts and bank trust companies) to apply their own procedures, provided that American Funds Service Company believes the intermediary’s procedures are reasonably designed to enforce the frequent trading policies of the fund. You should refer to disclosures provided by the intermediaries with

27 The Income Fund of America / Prospectus

which you have an account to determine the specific trading restrictions that apply to you.

If American Funds Service Company identifies any activity that may constitute frequent trading, it reserves the right to contact the intermediary and request that the intermediary either provide information regarding an account owner’s transactions or restrict the account owner’s trading. If American Funds Service Company is not satisfied that the intermediary has taken appropriate action, American Funds Service Company may terminate the intermediary’s ability to transact in fund shares.

There is no guarantee that all instances of frequent trading in fund shares will be prevented.

Notwithstanding the fund’s surveillance procedures described above, all transactions in fund shares remain subject to the right of the fund, Capital Client Group, Inc. and American Funds Service Company to restrict potentially abusive trading generally, including the types of transactions described above that will not be prevented. See the statement of additional information for more information about how American Funds Service Company may address other potentially abusive trading activity in American Funds.

Distributions and taxes

Dividends and distributions The fund intends to distribute dividends to you, usually in March, June, September and December.

Capital gains, if any, are usually distributed in December. When a dividend or capital gain is distributed, the net asset value per share is reduced by the amount of the payment.

You may elect to reinvest dividends and/or capital gain distributions to purchase additional shares of this fund or other American Funds, or you may elect to receive them in cash. Dividends and capital gain distributions for 529 share classes and retirement plan shareholders will be reinvested automatically.

Taxes on dividends and distributions For federal tax purposes, dividends and distributions of short-term capital gains are taxable as ordinary income. If you are an individual and meet certain holding period requirements with respect to your fund shares, you may be eligible for reduced tax rates on “qualified dividend income,” if any, distributed by the fund to you. The fund’s distributions of net long-term capital gains are taxable as long-term capital gains. Any dividends or capital gain distributions you receive from the fund will normally be taxable to you when made, regardless of whether you reinvest dividends or capital gain distributions or receive them in cash.

Dividends and capital gain distributions that are automatically reinvested in a tax-favored retirement or education savings account do not result in federal or state income tax at the time of reinvestment.

Taxes on transactions Your redemptions, including exchanges, may result in a capital gain or loss for federal tax purposes. A capital gain or loss on your investment is the difference between the cost of your shares, including any sales charges, and the amount you receive when you sell them.

Exchanges within a tax-favored retirement plan account will not result in a capital gain or loss for federal or state income tax purposes. With limited exceptions, distributions from a retirement plan account are taxable as ordinary income.

Shareholder fees Fees borne directly by the fund normally have the effect of reducing a shareholder’s taxable income on distributions.

Please see your tax advisor for more information. Holders of Class 529 shares should refer to the applicable program description for more information regarding the tax consequences of selling Class 529 shares.

Choosing a share class The fund offers different classes of shares through this prospectus. The services or share classes available to you may vary depending upon how you wish to purchase shares of the fund.

Each share class represents an investment in the same portfolio of securities, but each class has its own sales charge and expense structure, allowing you to choose the class that best fits your situation. For example, while Class F-1 shares are subject to 12b-1 fees and subtransfer agency fees payable to third-party service providers, Class F-2 shares are subject only to subtransfer agency fees payable to third-party service providers (and not 12b-1 fees) and Class F-3 shares are not subject to any such additional fees. The different fee structures allow the investor to choose how to pay for advisory platform expenses. Class R shares offer different levels of 12b-1 and recordkeeping fees so that a plan can choose the class that best meets the cost associated with obtaining investment related services and participant level recordkeeping for the plan. When you purchase shares of the fund for an individual-type account, you should choose a share class. If none is chosen, your investment will be made in Class A shares or, in the case of a 529 plan investment, Class 529-A shares (or, if you are investing through a financial intermediary who offers only Class T and 529-T shares, your investment will be made in Class T or Class 529-T shares, as applicable).

Factors you should consider when choosing a class of shares include:

· how long you expect to own the shares;

· how much you intend to invest;

· total expenses associated with owning shares of each class;

· whether you qualify for any reduction or waiver of sales charges (for example, Class A or 529-A or Class T or 529-T shares may be a less expensive option over time, particularly if you qualify for a sales charge reduction or waiver);

· whether you want or need the flexibility to effect exchanges among American Funds without the imposition of a sales charge (for example, while Class A shares offer such exchange privileges, Class T shares do not);

· whether you plan to take any distributions in the near future (for example, the contingent deferred sales charge will not be waived if you sell your Class 529-C shares to cover higher education expenses); and

· availability of share classes:

— Class C shares are not available to retirement plans that do not currently invest in such shares and that are eligible to invest in Class R shares, including retirement plans established under Internal Revenue Code Sections 401(a) (including 401(k) plans), 403(b) or 457;

— Class F and 529-F shares are available, as applicable, (i) to fee-based programs of investment dealers that have special agreements with the fund’s distributor, (ii) to financial intermediaries that have been approved by, and that have special agreements with, the fund’s distributor to offer Class F and 529-F shares to self-directed investment brokerage accounts that may charge a transaction fee, (iii) to certain registered investment advisors and (iv) to other intermediaries approved by the fund’s distributor;

— Class F-3 shares (but not Class 529-F-3 shares) are also available to institutional investors, which include, but are not limited to, charitable organizations, governmental institutions, corporations and financial intermediaries. For accounts

The Income Fund of America / Prospectus 30

held and serviced by the fund’s transfer agent the minimum investment amount is $1 million; and

— Class R shares are available (i) to retirement plans established under Internal Revenue Code Sections 401(a) (including 401(k) plans), 403(b) or 457, (ii) to nonqualified deferred compensation plans and certain voluntary employee benefit association and post-retirement benefit plans, (iii) to certain institutional investors (including, but not limited to, certain charitable organizations), (iv) to certain registered investment companies approved by the fund’s investment adviser or distributor and (v) to other institutional-type accounts.

Each investor’s financial considerations are different. You should speak with your financial professional to help you decide which share class is best for you.

31 The Income Fund of America / Prospectus

Sales charges

Class A and 529-A shares The initial sales charge you pay each time you buy Class A or 529-A shares differs depending upon the amount you invest and may be reduced or eliminated for larger purchases as indicated below. The “offering price,” the price you pay to buy shares, includes any applicable sales charge, which will be deducted directly from your investment. Shares acquired through reinvestment of dividends or capital gain distributions are not subject to an initial sales charge.

Class A shares


	Sales charge as a percentage of:
Investment	Offering price	Net amount invested	Dealer commission as a percentage of offering price
Less than $25,000	5.75%	6.10%	5.00%
$25,000 but less than $50,000	5.00	5.26	4.25
$50,000 but less than $100,000	4.50	4.71	3.75
$100,000 but less than $250,000	3.50	3.63	2.75
$250,000 but less than $500,000	2.50	2.56	2.00
$500,000 but less than $750,000	2.00	2.04	1.60
$750,000 but less than $1 million	1.50	1.52	1.20
$1 million or more and certain other investments described below	none	none	see below

Class 529-A shares


	Sales charge as a percentage of:
Investment	Offering price	Net amount invested	Dealer commission as a percentage of offering price
Less than $250,000	3.50%	3.63%	2.75%
$250,000 but less than $500,000	2.50	2.56	2.00
$500,000 but less than $750,000	2.00	2.04	1.60
$750,000 but less than $1 million	1.50	1.52	1.20
$1 million or more and certain other investments described below	none	none	see below

The sales charge, expressed as a percentage of the offering price or the net amount invested, may be higher or lower than the percentages described in the table above due to rounding. This is because the dollar amount of the sales charge is determined by subtracting the net asset value of the shares purchased from the offering price, which is calculated to two decimal places using standard rounding criteria. The impact of rounding will vary with the size of the investment and the net asset value of the shares. Similarly, any contingent deferred sales charge paid by you on investments in Class A or 529-A shares may be higher or lower than the 1% charge described below due to rounding.

The Income Fund of America / Prospectus 32

Except as provided below, investments in Class A shares of $1 million or more will be subject to a 1% contingent deferred sales charge if the shares are sold within 18 months of purchase. The contingent deferred sales charge is based on the original purchase cost or the current market value of the shares being sold, whichever is less.

Class A share purchases not subject to sales charges The following investments are not subject to any initial or contingent deferred sales charge if American Funds Service Company is properly notified of the nature of the investment:

· investments made by accounts that are part of qualified fee-based programs that purchased Class A shares before the discontinuation of the relevant investment dealer’s load-waived Class A share program with American Funds and that continue to be held through fee-based programs;

· rollover investments from retirement plans to IRAs that are described in the “Rollovers from retirement plans to IRAs” section of this prospectus;

· investments made by accounts held at American Funds Service Company that are no longer associated with a financial professional may invest in Class A shares without a sales charge. This includes retirement plans investing in Class A shares, where the plan is no longer associated with a financial professional. SIMPLE IRAs and 403(b) custodial accounts that are aggregated at the plan level for Class A sales charge purposes are not eligible to invest without a sales charge under this policy; and

· Investments made by accounts held through banks and bank trust companies that charge a fee for custodial services and do not have a financial professional assigned to the account.

The distributor may pay dealers a commission of up to 1% on investments made in Class A shares with no initial sales charge. The fund may reimburse the distributor for these payments through its plans of distribution (see “Plans of distribution” in this prospectus).

A transfer from the Virginia Prepaid Education Program^SM or the Virginia Education Savings Trust^SM to a CollegeAmerica^®account will be made with no sales charge. No commission will be paid to the dealer on such a transfer. Investment dealers will be compensated solely with an annual service fee that begins to accrue immediately.

If requested, American Funds Class A shares will be sold at net asset value to:

The Income Fund of America / Prospectus 34

Class T shares The initial sales charge you pay each time you buy Class T shares differs depending upon the amount you invest and may be reduced for larger purchases as indicated below. The “offering price,” the price you pay to buy shares, includes any applicable sales charge, which will be deducted directly from your investment. Shares acquired through reinvestment of dividends or capital gain distributions are not subject to an initial sales charge.

See “Plans of distribution” in this prospectus for ongoing compensation paid to your financial professional for all share classes.

Contingent deferred sales charges Shares acquired through reinvestment of dividends or capital gain distributions are not subject to a contingent deferred sales charge. In addition, the contingent deferred sales charge may be waived in certain circumstances. See “Contingent deferred sales charge waivers” in the “Sales charge reductions and waivers” section of this prospectus. For purposes of determining the contingent deferred sales charge, if you sell only some of your shares, shares that are not subject to any contingent deferred sales charge will be sold first, followed by shares that you have owned the longest.

35 The Income Fund of America / Prospectus

Sales charge reductions and waivers To receive a reduction in your Class A initial sales charge, you must let your financial professional or American Funds Service Company know at the time you purchase shares that you qualify for such a reduction. If you do not let your financial professional or American Funds Service Company know that you are eligible for a reduction, you may not receive the sales charge discount to which you are otherwise entitled. In order to determine your eligibility to receive a sales charge discount, it may be necessary for you to provide your financial professional or American Funds Service Company with information and records (including account statements) of all relevant accounts invested in American Funds. You may need to invest directly through American Funds Service Company in order to receive the sales charge waivers described in this prospectus. Investors should consult their financial intermediary for further information. Certain financial intermediaries that distribute shares of American Funds may impose different sales charge waivers than those described in this prospectus. Such variations in sales charge waivers are described in an appendix to this prospectus titled “Sales charge waivers.” Note that such sales charge waivers and discounts offered through a particular intermediary, as set forth in the appendix to this prospectus, are implemented and administered solely by that intermediary. Please contact the applicable intermediary to ensure that you understand the steps you must take in order to qualify for any available waivers or discounts.

In addition to the information in this prospectus, you may obtain more information about share classes, sales charges and sales charge reductions and waivers through a link on the home page of our website at capitalgroup.com, from the statement of additional information or from your financial professional.

Reducing your Class A initial sales charge Consistent with the policies described in this prospectus, you and your “immediate family” (your spouse — or equivalent, if recognized under local law, your children under the age of 21 or disabled adult dependents covered by ABLE accounts) may combine all of your American Funds investments to reduce Class A sales charges. In addition, two or more retirement plans of an employer or an employer’s affiliates may combine all of their American Funds investments to reduce Class A sales charges. However, for this purpose, investments representing direct purchases of American Funds U.S. Government Money Market Fund Class A shares are excluded. Following are different ways that you may qualify for a reduced Class A sales charge:

Aggregating accounts To receive a reduced Class A sales charge, investments made by you and your immediate family (see above) may be aggregated if made for your own account(s) and/or certain other accounts, such as:

· individual-type employee benefit plans, such as an IRA, single-participant Keogh-type plan, or a participant account of a 403(b) plan that is treated as an individual-type plan for sales charge purposes (see “Purchases by certain 403(b) plans” under “Rollovers from retirement plans to IRAs” below);

· SEP plans and SIMPLE IRA plans established after November 15, 2004, by an employer adopting any plan document other than a prototype plan produced by Capital Client Group, Inc.;

· business accounts solely controlled by you or your immediate family (for example, you own the entire business);

The Income Fund of America / Prospectus 36

· trust accounts established by you or your immediate family (for trusts with only one primary beneficiary, upon the trustor’s death the trust account may be aggregated with such beneficiary’s own accounts; for trusts with multiple primary beneficiaries, upon the trustor’s death the trustees of the trust may instruct American Funds Service Company to establish separate trust accounts for each primary beneficiary; each primary beneficiary’s separate trust account may then be aggregated with such beneficiary’s own accounts);

· endowments or foundations established and controlled by you or your immediate family; or

· 529 accounts, which will be aggregated at the account owner level (Class 529-E accounts may only be aggregated with an eligible employer plan).

Individual purchases by a trustee(s) or other fiduciary(ies) may also be aggregated if the investments are:

· for a single trust estate or fiduciary account, including employee benefit plans other than the individual-type employee benefit plans described above;

· made for two or more employee benefit plans of a single employer or of affiliated employers as defined in the 1940 Act, excluding the individual-type employee benefit plans described above;

· for a diversified common trust fund or other diversified pooled account not specifically formed for the purpose of accumulating fund shares;

· for nonprofit, charitable or educational organizations, or any endowments or foundations established and controlled by such organizations, or any employer-sponsored retirement plans established for the benefit of the employees of such organizations, their endowments, or their foundations;

· for participant accounts of a 403(b) plan that is treated as an employer-sponsored plan for sales charge purposes (see “Purchases by certain 403(b) plans” under “Rollovers from retirement plans to IRAs” below), or made for participant accounts of two or more such plans, in each case of a single employer or affiliated employers as defined in the 1940 Act; or

· for a SEP or SIMPLE IRA plan established after November 15, 2004, by an employer adopting a prototype plan produced by Capital Client Group, Inc.

Purchases made for nominee or street name accounts (securities held in the name of an investment dealer or another nominee such as a bank trust department instead of the customer) may not be aggregated with those made for other accounts and may not be aggregated with other nominee or street name accounts unless otherwise qualified as described above.

Joint accounts may be aggregated with other accounts belonging to the primary owner and/or his or her immediate family. The primary owner of a joint account is the individual responsible for taxes on the account.

Investments made through employer-sponsored retirement plan accounts will not be aggregated with individual-type accounts.

Concurrent purchases You may reduce your Class A sales charge by combining simultaneous purchases (including, upon your request, purchases for gifts) of all classes of shares in American Funds. Shares of American Funds U.S. Government Money Market Fund purchased through an exchange, reinvestment or

37 The Income Fund of America / Prospectus

cross-reinvestment from a fund having a sales charge also qualify. However, direct purchases of American Funds U.S. Government Money Market Fund Class A shares are excluded. If you currently have individual holdings in American Legacy variable annuity contracts or variable life insurance policies that were established on or before March 31, 2007, you may continue to combine purchases made under such contracts and policies to reduce your Class A sales charge.

Rights of accumulation Subject to the limitations described in the aggregation policy, you may take into account your accumulated holdings in all share classes of American Funds to determine your sales charge on investments in accounts eligible to be aggregated. Direct purchases of American Funds U.S. Government Money Market Fund Class A shares are excluded. Subject to your investment dealer’s or recordkeeper’s capabilities, your accumulated holdings will be calculated as the higher of (a) the current value of your existing holdings (the “market value”) as of the day prior to your American Funds investment or (b) the amount you invested (including reinvested dividends and capital gains, but excluding capital appreciation) less any withdrawals (the “cost value”). Depending on the entity on whose books your account is held, the value of your holdings in that account may not be eligible for calculation at cost value. For example, accounts held in nominee or street name may not be eligible for calculation at cost value and instead may be calculated at market value for purposes of rights of accumulation.

The value of all of your holdings in accounts established in calendar year 2005 or earlier will be assigned an initial cost value equal to the market value of those holdings as of the last business day of 2005. Thereafter, the cost value of such accounts will increase or decrease according to actual investments or withdrawals. You must contact your financial professional or American Funds Service Company if you have additional information that is relevant to the calculation of the value of your holdings.

When determining your American Funds Class A sales charge, if your investment is not in an employer-sponsored retirement plan, you may also continue to take into account the market value (as of the day prior to your American Funds investment) of your individual holdings in various American Legacy variable annuity contracts and variable life insurance policies that were established on or before March 31, 2007. An employer-sponsored retirement plan may also continue to take into account the market value of its investments in American Legacy Retirement Investment Plans that were established on or before March 31, 2007.

You may not purchase Class C or 529-C shares if such combined holdings cause you to be eligible to purchase Class A or 529-A shares at the $1 million or more sales charge discount rate (i.e., at net asset value).

If you make a gift of American Funds Class A shares, upon your request, you may purchase the shares at the sales charge discount allowed under rights of accumulation of all of your American Funds and applicable American Legacy accounts.

You should retain any records necessary to substantiate the historical amounts you have invested.

Statement of intention You may reduce your Class A sales charge by establishing a statement of intention. A statement of intention is a nonbinding commitment that allows you to combine all purchases of all American Funds share classes (excluding

The Income Fund of America / Prospectus 38

American Funds U.S. Government Money Market Fund) that you intend to make over a 13-month period to determine the applicable sales charge; however, purchases made under a right of reinvestment, appreciation of your holdings, and reinvested dividends and capital gains do not count as purchases made during the statement period. Your accumulated holdings (as described and calculated under “Rights of accumulation” above) eligible to be aggregated as of the day immediately before the start of the statement period may be credited toward satisfying the statement. A portion of your account may be held in escrow to cover additional Class A sales charges that may be due if your total purchases over the statement period do not qualify you for the applicable sales charge reduction. Employer-sponsored retirement plans are restricted from establishing statements of intention. See the discussion regarding employer-sponsored retirement plans under “Purchase, exchange and sale of shares” in this prospectus for more information.

The statement of intention period starts on the date on which your first purchase made toward satisfying the statement of intention is processed. Your accumulated holdings (as described above under “Rights of accumulation”) eligible to be aggregated as of the day immediately before the start of the statement of intention period may be credited toward satisfying the statement of intention.

You may revise the commitment you have made in your statement of intention upward at any time during the statement of intention period. If your prior commitment has not been met by the time of the revision, the statement of intention period during which purchases must be made will remain unchanged. Purchases made from the date of the revision will receive the reduced sales charge, if any, resulting from the revised statement of intention. If your prior commitment has been met by the time of the revision, your original statement of intention will be considered met and a new statement of intention will be established.

The statement of intention will be considered completed if the shareholder dies within the 13-month statement of intention period. Commissions to dealers will not be adjusted or paid on the difference between the statement of intention amount and the amount actually invested before the shareholder’s death.

When a shareholder elects to use a statement of intention, shares equal to 5% of the dollar amount specified in the statement of intention may be held in escrow in the shareholder’s account out of the initial purchase (or subsequent purchases, if necessary) by American Funds Service Company. All dividends and any capital gain distributions on shares held in escrow will be credited to the shareholder’s account in shares (or paid in cash, if requested). If the intended investment is not completed within the specified statement of intention period the investments made during the statement period will be adjusted to reflect the difference between the sales charge actually paid and the sales charge which would have been paid if the total of such purchases had been made at a single time. Any dealers assigned to the shareholder’s account at the time a purchase was made during the statement period will receive a corresponding commission adjustment if appropriate.

In addition, if you currently have individual holdings in American Legacy variable annuity contracts or variable life insurance policies that were established on or before March 31, 2007, you may continue to apply purchases under such contracts and policies to a statement of intention.

39 The Income Fund of America / Prospectus

Shareholders purchasing shares at a reduced sales charge under a statement of intention indicate their acceptance of these terms and those in the prospectus with their first purchase.

Reducing your Class T initial sales charge Consistent with the policies described in this prospectus, the initial sales charge you pay each time you buy Class T shares may differ depending upon the amount you invest and may be reduced for larger purchases. Additionally, Class T shares acquired through reinvestment of dividends or capital gain distributions are not subject to an initial sales charge. Sales charges on Class T shares are applied on a transaction-by-transaction basis, and, accordingly, Class T shares are not eligible for any other sales charge waivers or reductions, including through the aggregation of Class T shares concurrently purchased by other related accounts or in other American Funds. The sales charge applicable to Class T shares may not be reduced by establishing a statement of intention, and rights of accumulation are not available for Class T shares.

Right of reinvestment If you notify American Funds Service Company prior to the time of reinvestment, you may reinvest proceeds from a redemption, dividend payment or capital gain distribution without a sales charge in the same fund or other American Funds, provided that the reinvestment occurs within 90 days after the date of the redemption, dividend payment or distribution and is made into the same account from which you redeemed the shares or received the dividend payment or distribution. If the account has been closed, you may reinvest without a sales charge if the new receiving account has the same registration as the closed account and the reinvestment is made within 90 days after the date of redemption, dividend payment or distribution.

Proceeds from a redemption and all dividend payments and capital gain distributions will be reinvested in the same share class from which the original redemption, dividend payment or distribution was made. Any contingent deferred sales charge on Class A or C shares will be credited to your account. Redemption proceeds of Class A shares representing direct purchases in American Funds U.S. Government Money Market Fund that are reinvested in other American Funds will be subject to a sales charge.

Proceeds will be reinvested at the next calculated net asset value after your request is received by American Funds Service Company, provided that your request contains all information and legal documentation necessary to process the transaction. For purposes of this “right of reinvestment policy,” automatic transactions (including, for example, automatic purchases, withdrawals and payroll deductions) and ongoing retirement plan contributions are not eligible for investment without a sales charge. This paragraph does not apply to certain rollover investments as described under “Rollovers from retirement plans to IRAs” in this prospectus. Depending on the financial intermediary holding your account, your reinvestment privileges may be unavailable or differ from those described in this prospectus. Investors should consult their financial intermediary for further information.

Contingent deferred sales charge waivers The contingent deferred sales charge on Class A and C shares will be waived in the following cases:

· permitted exchanges of shares, except if shares acquired by exchange are then redeemed within the period during which a contingent deferred sales charge would apply to the initial shares purchased;

· tax-free returns of excess contributions to IRAs;

The Income Fund of America / Prospectus 40

· redemptions due to death or postpurchase disability of the shareholder (this generally excludes accounts registered in the names of trusts and other entities);

· in the case of joint tenant accounts, if one joint tenant dies, a surviving joint tenant, at the time he or she notifies American Funds Service Company of the other joint tenant’s death and removes the decedent’s name from the account, may redeem shares from the account without incurring a contingent deferred sales charge; however, redemptions made after American Funds Service Company is notified of the death of a joint tenant will be subject to a contingent deferred sales charge;

· for 529 share classes only, redemptions due to a beneficiary’s death, postpurchase disability or receipt of a scholarship (to the extent of the scholarship award);

· redemptions due to the complete termination of a trust upon the death of the trustor/grantor or beneficiary, but only if such termination is specifically provided for in the trust document;

· shares redeemed at the discretion of American Funds Service Company for accounts that do not meet the fund’s minimum investment requirements, as described in this prospectus; and

· the following types of transactions, if they do not exceed 12% of the value of an account annually:

— required minimum distributions taken from retirement accounts in accordance with IRS regulations; and

— redemptions through an automatic withdrawal plan (“AWP”) (see “Automatic withdrawals” under “Shareholder account services and privileges” in the statement of additional information). For each AWP payment, assets that are not subject to a contingent deferred sales charge, such as shares acquired through reinvestment of dividends and/or capital gain distributions, will be redeemed first and will count toward the 12% limit. If there is an insufficient amount of assets not subject to a contingent deferred sales charge to cover a particular AWP payment, shares subject to the lowest contingent deferred sales charge will be redeemed next until the 12% limit is reached. Any dividends and/or capital gain distributions taken in cash by a shareholder who receives payments through an AWP will also count toward the 12% limit. In the case of an AWP, the 12% limit is calculated at the time an automatic redemption is first made, and is recalculated at the time each additional automatic redemption is made. Shareholders who establish an AWP should be aware that the amount of a payment not subject to a contingent deferred sales charge may vary over time depending on fluctuations in the value of their accounts. This privilege may be revised or terminated at any time.

For purposes of this paragraph, “account” means your investment in the applicable class of shares of the particular fund from which you are making the redemption.

The contingent deferred sales charge on American Funds Class A shares may be waived in cases where the fund’s transfer agent determines the benefit to the fund of collecting the contingent deferred sales charge would be outweighed by the cost of applying it.

Contingent deferred sales charge waivers are allowed only in the cases listed here and in the statement of additional information. For example, contingent deferred sales charge waivers will not be allowed on redemptions of Class 529-C shares due to termination of CollegeAmerica; a determination by the Internal Revenue Service that CollegeAmerica

41 The Income Fund of America / Prospectus

does not qualify as a qualified tuition program under the Code; proposal or enactment of law that eliminates or limits the tax-favored status of CollegeAmerica; or elimination of the fund by Commonwealth Savers Plan^SM (formerly, Virginia529) as an option for additional investment within CollegeAmerica.

To have your Class A or C contingent deferred sales charge waived, you must inform your financial professional or American Funds Service Company at the time you redeem shares that you qualify for such a waiver.

Other sales charge waivers Purchases of Class A shares through a self-clearing broker-dealer firm generally incur a sales charge. However, self-clearing broker-dealer firms may extend the 90 day right of reinvestment to allow reinvestment in Class A shares without a sales charge in cases where fund shareholders request reinvestment of a required minimum distribution from an Individual Retirement Account if such requirement is waived by regulation or legislation (“waived RMD reinvestment”), provided that the self-clearing broker-dealer firm has specific language in this prospectus to such effect. If a self-clearing firm does not have their own policies listed in the prospectus, waived RMD reinvestments are not available without a sales charge. Firm specific language is located in the appendix to the prospectus. A self-clearing broker-dealer firm is a firm that holds some or all of the assets in your account, executes trades for the assets held on its platform internally rather than through the fund’s transfer agent or a third-party clearing firm and provides account statements and tax reporting to you. The largest broker-dealer firms are typically self-clearing. For all other broker-dealer firms, shares purchased through a waived RMD reinvestment are available at net asset value. For accounts held with the fund’s transfer agent, waived RMD reinvestments in Class A shares are not subject to sales charges.

Purchases of Class 529-A shares through (i) a rollover from another 529 plan or (ii) a recontribution of a refunded qualified education expense are not subject to sales charges.

If you have any questions, ask your financial professional whether Class A or 529-A shares purchased through these policies are available without a sales charge. Recontributions or waived RMD investments distributed from Class 529-C or Class C shares will be reinvested in the same share class from which the distribution was made. In addition, any contingent deferred sales charge paid on Class 529-A/Class A and Class 529-C/Class C share distributions under these policies will be credited to your account when reinvested.

Waivers of all or a portion of the contingent deferred sales charge on Class C and 529-C shares and the sales charge on Class A and 529-A shares will be granted for transactions requested by financial intermediaries as a result of (i) pending or anticipated regulatory matters that require investor accounts to be moved to a different share class or (ii) conversions of IRAs from brokerage to advisory accounts investing in Class F shares in cases where new investments in brokerage IRA accounts have been restricted by the intermediary.

Rollovers from CollegeAmerica to Roth IRAs Proceeds of a CollegeAmerica plan account may be rolled over in a direct trustee-to-trustee transfer to the plan beneficiary’s Capital Bank and Trust Roth IRA and invested in Class A shares without a sales charge, provided that such rollover is intended to satisfy the requirements of the Internal

The Income Fund of America / Prospectus 42

Revenue Code. If you hold CollegeAmerica or Roth IRA accounts through a financial intermediary its policies may differ.

Rollovers from retirement plans to IRAs Assets from retirement plans may be invested in Class A, C or F shares through an IRA rollover, subject to the other provisions of this prospectus. Class C shares are not available if the assets are being rolled over from investments held in American Funds Recordkeeper Direct and PlanPremier retirement plan recordkeeping programs.

Rollovers to IRAs from retirement plans that are rolled into Class A shares will be subject to applicable sales charges. The following rollovers to Class A shares will be made without a sales charge:

· rollovers to Capital Bank and Trust Company IRAs if the assets were invested in any fund managed by the investment adviser or its affiliates at the time of distribution;

· rollovers to IRAs from 403(b) plans with Capital Bank and Trust Company as custodian; and

· rollovers to Capital Bank and Trust Company IRAs from investments held in American Funds Recordkeeper Direct and PlanPremier retirement plan recordkeeping programs.

IRA rollover assets that roll over without a sales charge as described above will not be subject to a contingent deferred sales charge, and investment dealers will be compensated solely with an annual service fee that begins to accrue immediately. All other rollovers invested in Class A shares, as well as future contributions to the IRA, will be subject to sales charges and to the terms and conditions generally applicable to Class A share investments as described in this prospectus and in the statement of additional information.

Purchases by SEP plans and SIMPLE IRA plans Participant accounts in a Simplified Employee Pension (SEP) plan or a Savings Incentive Match Plan for Employees of Small Employers IRA (SIMPLE IRA) will be aggregated at the plan level for Class A sales charge purposes if an employer adopts a prototype plan produced by Capital Client Group, Inc. or (a) the employer or plan sponsor submits all contributions for all participating employees in a single contribution transmittal or the contributions are identified as related to the same plan; (b) each transmittal is accompanied by checks or wire transfers and generally must be submitted through the transfer agent’s automated contribution system if held on the fund’s books; and (c) if the fund is expected to carry separate accounts in the name of each plan participant and (i) the employer or plan sponsor notifies the funds’ transfer agent or the intermediary holding the account that the separate accounts of all plan participants should be linked and (ii) all new participant accounts are established by submitting the appropriate documentation on behalf of each new participant. Participant accounts in a SEP or SIMPLE plan that are eligible to aggregate their assets at the plan level may not also aggregate the assets with their individual accounts.

Purchases by certain 403(b) plans A 403(b) plan may not invest in American Funds Class A or C shares unless such plan was invested in Class A or C shares before January 1, 2009.

Participant accounts of a 403(b) plan that invested in American Funds Class A or C shares and were treated as an individual-type plan for sales charge purposes before January 1, 2009, may continue to be treated as accounts of an individual-type plan for sales charge

43 The Income Fund of America / Prospectus

purposes. Participant accounts of a 403(b) plan that invested in American Funds Class A or C shares and were treated as an employer-sponsored plan for sales charge purposes before January 1, 2009, may continue to be treated as accounts of an employer-sponsored plan for sales charge purposes. Participant accounts of a 403(b) plan that was established on or after January 1, 2009, are treated as accounts of an employer-sponsored plan for sales charge purposes.

Moving between accounts American Funds investments by certain account types may be moved to other account types without incurring additional Class A sales charges. These transactions include:

· redemption proceeds from a non-retirement account (for example, a joint tenant account) used to purchase fund shares in an IRA or other individual-type retirement account;

· required minimum distributions from an IRA or other individual-type retirement account used to purchase fund shares in a non-retirement account; and

· death distributions paid to a beneficiary’s account that are used by the beneficiary to purchase fund shares in a different account.

These privileges are generally available only if your account is held directly with the fund’s transfer agent or if the financial intermediary holding your account has the systems, policies and procedures to support providing the privileges on its systems. Investors should consult their financial intermediary for further information.

Plans of distribution The fund has plans of distribution, or “12b-1 plans,” for certain share classes under which it may finance activities intended primarily to sell shares, provided that the categories of expenses are approved in advance by the fund’s board of trustees. The plans provide for payments, based on annualized percentages of average daily net assets, of:


Up to:	Share class(es)
0.25%	Class A shares
0.50%	Class T, F-1, 529-A, 529-T, 529-F-1 and R-4 shares
0.75%	Class 529-E and R-3 shares
0.85%	Class R-2E shares
1.00%	Class C, 529-C, R-1 and R-2 shares

For all share classes indicated above, up to .25% may be used to pay service fees to qualified dealers for providing certain shareholder services. The amount remaining for each share class, if any, may be used for distribution expenses.

The 12b-1 fees paid by each applicable share class of the fund, as a percentage of average net assets for the most recent fiscal year, are indicated in the Annual Fund Operating Expenses table under “Fees and expenses of the fund” in this prospectus. Since these fees are paid out of the fund’s assets on an ongoing basis, over time they may cost you more than paying other types of sales charges or service fees and reduce the return on your investment. The higher fees for Class C shares may cost you more over time than paying the initial sales charge for Class A or T shares.

The Income Fund of America / Prospectus 44

Other compensation to dealers Capital Client Group, Inc., at its expense, provides additional compensation to investment dealers. These payments may be made, at the discretion of Capital Client Group, Inc., to no more than the top 60 dealers (or their affiliates) with which it has a substantive distribution relationship involving the sale of American Funds. The amount will be determined using a formula applied consistently to dealers based on their assets under management. The level of payments made to a qualifying firm under the formula will not exceed .035% of eligible American Funds assets attributable to that dealer. Eligible assets are all American Funds assets other than Class R shares, Class F-3 shares, Class F shares held in IRAs and shares held in certain retirement accounts. Dealers may direct Capital Client Group, Inc. to exclude additional assets. In addition to the asset-based payment, Capital Client Group, Inc. provides $5 million to certain firms based on their engagement with Capital Client Group, Inc. and the level of American Funds assets under management at each such firm to recognize the commitment each of those firms has made to collaborating with Capital Client Group, Inc. on achieving advisor training and education objectives. In 2023, Capital Client Group, Inc. paid this amount to the following firms:


Edward Jones	Morgan Stanley Wealth Management
LPL Financial LLC	Raymond James Group
Merrill Lynch, Pierce, Fenner & Smith	Wells Fargo Advisors

Capital Client Group, Inc. compensates the firms to support various efforts, including, among other things, to:

· help defray the costs incurred by qualifying dealers in connection with efforts to educate financial professionals about American Funds so that they can make recommendations and provide services that are suitable and meet shareholder needs;

· help defray the costs associated with the dealer firms’ provision of account related services and activities and support the dealer firms’ distribution activities;

· support meetings, conferences or other training and educational events hosted by the firm, and obtain relevant data regarding financial professional activities to facilitate Capital Client Group, Inc.’s training and education activities; and

· make the American Funds available through firm distribution platforms and related sales infrastructure.

Capital Client Group, Inc. will, on an annual basis, determine the advisability of continuing these payments. Firms receiving additional compensation payments must sign a letter acknowledging the purpose of the payment and generally requiring the firms to (1) perform the due diligence necessary to include American Funds on their platform, (2) not provide financial professionals, branch managers or associated persons with any financial incentives to promote the sales of one approved fund group over another approved group, (3) provide opportunities for their clients to obtain individualized advice, (4) provide Capital Client Group, Inc. broad access to their financial professionals and product platforms and work together on mutual business objectives, and (5) work with the fund’s transfer agent to promote operational efficiencies and to facilitate necessary communication between American Funds and the firm’s clients who own shares of American Funds.

Separately, Capital Client Group, Inc. has identified certain firms that provide a self-directed platform for the public as well as clearing, custody and recordkeeping services

45 The Income Fund of America / Prospectus

for certain other intermediaries. In lieu of the formula described above, these firms receive up to .018% of assets under administration (excluding assets where the firm acts as a fiduciary and Class R shares). Firms may direct Capital Client Group, Inc. to exclude additional assets.

In addition to compensation through the formulas described above, Capital Client Group, Inc. makes payments to certain financial intermediaries for client account maintenance support, statement preparation, and transaction processing. These payments are based on the average daily net asset value of fund shares held by the intermediary and are in addition to any amounts paid by the fund.

Capital Client Group, Inc. also provides compensation for, among other things, data (including fees to obtain information on financial professionals to better tailor training and education opportunities), operational improvements, support for transaction fees, technology enhancements and specific training, education and marketing opportunities. The largest payments by Capital Client Group, Inc. in 2023 for these services are listed below.

If investment advisers, distributors or other affiliates of mutual funds pay additional compensation or other incentives to investment dealers in differing amounts, dealer firms and their financial professionals may have financial incentives for recommending a particular mutual fund over other mutual funds or investments, creating a potential conflict of interest. You should consult with your financial professional and review carefully any disclosure by your financial professional’s firm as to compensation received.

Fund expenses Note that, unless otherwise stated, references to Class A, C, T and F shares in this “Fund expenses” section do not include the corresponding Class 529 shares.

In periods of market volatility, assets of the fund may decline significantly, causing total annual fund operating expenses (as a percentage of the value of your investment) to become higher than the numbers shown in the Annual Fund Operating Expenses table under “Fees and expenses of the fund” in this prospectus.

For all share classes, “Other expenses” items in the Annual Fund Operating Expenses table in this prospectus include fees for administrative services provided by the fund’s investment adviser and its affiliates. Administrative services are provided by the investment adviser and its affiliates to help assist third parties providing non-distribution services to fund shareholders. These services include providing in-depth information on the fund and market developments that impact fund investments. Administrative services also include, but are not limited to, coordinating, monitoring and overseeing third parties that provide services to fund shareholders. The Administrative Services Agreement between the fund and the investment adviser provides the fund the ability to charge an administrative services fee of .05% for all share classes. The fund’s investment adviser receives an administrative services fee at the annual rate of .03% of the average daily net assets of the fund attributable to Class A, C, T, F, R and 529 shares (which could be increased as noted above) for its provision of administrative services.

The “Other expenses” items in the Annual Fund Operating Expenses table also include custodial, legal and transfer agent (and, if applicable, subtransfer agent/recordkeeping) payments and various other expenses applicable to all share classes.

47 The Income Fund of America / Prospectus

Subtransfer agency and recordkeeping fees Subtransfer agent/recordkeeping payments may be made to third parties (including affiliates of the fund’s investment adviser) that provide subtransfer agent, recordkeeping and/or shareholder services with respect to certain shareholder accounts in lieu of the transfer agent providing such services. The amount paid for subtransfer agent/recordkeeping services varies depending on the share class and services provided, and typically ranges from $3 to $18 per account. Although Class F-3 and Class 529-F-3 shares are not subject to any subtransfer agency or recordkeeping fees, Class F-1 and F-2 shares (and the corresponding Class 529 shares) are subject to subtransfer agency fees of up to .12% of fund assets.

For employer-sponsored retirement plans, the amount paid for subtransfer agent/ recordkeeping services varies depending on the share class selected. The table below shows the maximum payments to entities providing these services to retirement plans.


	Payments
Class A	0.05% of assets or $12 per participant position^*
Class R-1	0.10% of assets
Class R-2	0.35% of assets
Class R-2E	0.20% of assets
Class R-3	0.15% of assets
Class R-4	0.10% of assets
Class R-5E	0.15% of assets
Class R-5	0.05% of assets
Class R-6	none

^*Payment amount depends on the date services commenced.

Fee to Commonwealth Savers Plan For Class 529 shares, an expense of up to a maximum of .09% paid to a state or states for oversight and administrative services is included as an “Other expenses” item.

Financial highlights The Financial Highlights table is intended to help you understand the fund’s results for the past five fiscal years (or, if shorter, the period of operations). Certain information reflects financial results for a single share of a particular class. The total returns in the table represent the rate that an investor would have earned or lost on an investment in the fund (assuming reinvestment of all dividends and capital gain distributions). Where indicated, figures in the table reflect the impact, if any, of certain reimbursements from Capital Research and Management Company. For more information about these reimbursements, see the fund’s statement of additional information and Form N-CSR. The information in the Financial Highlights table has been audited by Deloitte & Touche LLP, whose current report, along with the fund’s financial statements, is included in the statement of additional information, which is available upon request.

Appendix

Sales charge waivers

The availability of certain sales charge waivers and discounts will depend on whether you purchase your shares directly from the fund or through a financial intermediary. Intermediaries may have different policies and procedures regarding the availability of front-end sales charge waivers or contingent deferred (back-end) sales charge (“CDSC”) waivers, which are discussed below. In all instances, it is the purchaser’s responsibility to notify the fund or the purchaser’s financial intermediary at the time of purchase of any relationship or other facts qualifying the purchaser for sales charge waivers or discounts. Please contact the applicable intermediary with any questions regarding how the intermediary applies the policies described below and to ensure that you understand what steps you must take to qualify for any available waivers or discounts. For waivers and discounts not available through a particular intermediary, shareholders will have to purchase fund shares directly from the fund or through another intermediary to receive these waivers or discounts. If you change intermediaries after you purchase fund shares, the policies and procedures of the new service provider (either your new intermediary or the fund’s transfer agent) will apply to your account. Those policies may be more or less favorable than those offered by the intermediary through which you purchased your fund shares. You should review any policy differences before changing intermediaries.

Class A shares front-end sales charge waivers available at Ameriprise Financial:

The following information applies to Class A shares purchases if you have an account with or otherwise purchase fund shares through Ameriprise Financial:

Effective May 24, 2021, shareholders purchasing fund shares through an Ameriprise Financial brokerage account are eligible for the following front-end sales charge waivers, which may differ from those disclosed elsewhere in this fund’s prospectus or SAI:

· Employer-sponsored retirement plans established prior to April 1, 2004 and that continue to meet the eligibility requirements in effect as of that date for purchasing Class A shares at net asset value (e.g., 401(k) plans, 457 plans, employer-sponsored 403(b) plans, profit sharing and money purchase pension plans and defined benefit plans). For purposes of this provision, employer-sponsored retirement plans do not include SEP IRAs, SIMPLE IRAs or SARSEPs

· Shares purchased through reinvestment of capital gains distributions and dividend reinvestment when purchasing shares of the same fund (but not any other fund within the same fund family)

· Shares exchanged from Class C shares of the same fund in the month of or following the 7-year anniversary of the purchase date. To the extent that this prospectus elsewhere provides for a waiver with respect to exchanges of Class C shares or conversion of Class C shares following a shorter holding period, that waiver will apply

· Employees and registered representatives of Ameriprise Financial or its affiliates and their immediate family members

· Shares purchased by or through qualified accounts (including IRAs, Coverdell Education Savings Accounts, 401(k)s, 403(b) TSCAs subject to ERISA and defined benefit plans established prior to April 1, 2004 that continue to meet the eligibility requirements in effect as of that date for purchasing Class A shares at net asset value) that are held by a covered family member, defined as an Ameriprise financial advisor and/or the advisor’s spouse, advisor’s lineal ascendant (mother, father, grandmother, grandfather, great

55 The Income Fund of America / Prospectus

Edward D. Jones & Co., L.P. (“Edward Jones”)

Policies Regarding Transactions Through Edward Jones

The following information has been provided by Edward Jones:

Effective on or after January 1, 2024, the following information supersedes prior information with respect to transactions and positions held in fund shares through an Edward Jones system. Clients of Edward Jones (also referred to as “shareholders”) purchasing fund shares on the Edward Jones commission and fee-based platforms are eligible only for the following sales charge discounts (also referred to as “breakpoints”) and waivers, which can differ from discounts and waivers described elsewhere in the mutual fund prospectus or statement of additional information (“SAI”) or through another broker-dealer. In all instances, it is the shareholder's responsibility to inform Edward Jones at the time of purchase of any relationship, holdings of American Funds, or other facts qualifying the purchaser for discounts or waivers. Edward Jones can ask for documentation of such circumstance. Shareholders should contact Edward Jones if they have questions regarding their eligibility for these discounts and waivers.

Breakpoints

· Breakpoint pricing, otherwise known as volume pricing, at dollar thresholds as described in the prospectus

Rights of Accumulation (“ROA”)

· The applicable sales charge on a purchase of Class A shares is determined by taking into account all share classes (except certain money market funds and any assets held in group retirement plans) of American Funds held by the shareholder or in an account grouped by Edward Jones with other accounts for the purpose of providing certain pricing considerations (“pricing groups”). If grouping assets as a shareholder, this includes all share classes held on the Edward Jones platform and/or held on another platform. The inclusion of eligible fund family assets in the ROA calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Money market funds are included only if such shares were sold with a sales charge at the time of purchase or acquired in exchange for shares purchased with a sales charge

· The employer maintaining a SEP IRA plan and/or SIMPLE IRA plan may elect to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping as opposed to including all share classes at a shareholder or pricing group level

· ROA is determined by calculating the higher of cost minus redemptions or market value (current shares x NAV)

57 The Income Fund of America / Prospectus

Letter of Intent (“LOI”)

· Through a LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders intend to make over a 13-month period from the date Edward Jones receives the LOI. The LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in combination with the value that the shareholder intends to buy over a 13-month period to calculate the front-end sales charge and any breakpoint discounts. Each purchase the shareholder makes during that 13-month period will receive the sales charge and breakpoint discount that applies to the total amount. The inclusion of eligible fund family assets in the LOI calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Purchases made before the LOI is received by Edward Jones are not adjusted under the LOI and will not reduce the sales charge previously paid. Sales charges will be adjusted if LOI is not met

· If the employer maintaining a SEP IRA plan and/or SIMPLE IRA plan has elected to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer

Sales Charge Waivers

Sales charges are waived for the following shareholders and in the following situations:

· Associates of Edward Jones and its affiliates and other accounts in the same pricing group (as determined by Edward Jones under its policies and procedures) as the associate. This waiver will continue for the remainder of the associate's life if the associate retires from Edward Jones in good-standing and remains in good standing pursuant to Edward Jones' policies and procedures

· Shares purchased in an Edward Jones fee-based program

· Shares purchased through reinvestment of capital gains distributions and dividend reinvestment

· Shares purchased from the proceeds of redeemed shares of the same fund family so long as the following conditions are met: the proceeds are from the sale of shares within 60 days of the purchase, the sale and purchase are made from a share class that charges a front load and one of the following (“Right of Reinstatement“):

— The redemption and repurchase occur in the same account

— The redemption proceeds are used to process an: IRA contribution, excess contributions, conversion, recharacterizing of contributions, or distribution, and the repurchase is done in an account within the same Edward Jones grouping for ROA

The Right of Reinstatement excludes systematic or automatic transactions including, but not limited to, purchases made through payroll deductions, liquidations to cover account fees, and reinvestments from non-mutual fund products.

· Shares exchanged into Class A shares from another share class so long as the exchange is into the same fund and was initiated at the discretion of Edward Jones. Edward Jones is responsible for any remaining CDSC due to the fund company, if applicable. Any future purchases are subject to the applicable sales charge as disclosed in the prospectus

· Exchanges from Class C shares to Class A shares of the same fund, generally, in the 84th month following the anniversary of the purchase date or earlier at the discretion of Edward Jones

The Income Fund of America / Prospectus 58

· Purchases of Class 529-A shares through a rollover from either another education savings plan or a security used for qualified distributions

· Purchases of Class 529-A shares made for recontribution of refunded amounts

Contingent Deferred Sales Charge (“CDSC”) Waivers

If the shareholder purchases shares that are subject to a CDSC and those shares are redeemed before the CDSC is expired, the shareholder is responsible to pay the CDSC except in the following conditions:

· The death or disability of the shareholder

· Systematic withdrawals with up to 10% per year of the account value
